Install amplifier + sub in trunk
So i was planning to put an amplifier and 2 subs in the trunk of my 05 w211 sedan .
The amplifier needs a + and - which i can easily get from the battery in the trunk.
The Amplifier also needs a low input + remote wire
My plan was to get a high level -> low level converter
And a High level -> remote converter
So my question is where would be the easiest place to pick up the High level input signal ?
I have Audio 20 system if that is for any help,
is there any cables around the rear deck / parcel shelf ?
made a quick overview schematic
Thanks in advance
